Buzzer not Woodpecker. And it is indeed odd that it’s stopped..

If only you knew my background...Anyway I do know the difference and we're just having fun.

My analyst background is saying that it either has been shut off or broken. If it was a Spy communication network it could be easily replaced by the Internet. If it was used for Military Communications, a closed fiber optics network would be the logical alternative which are more secure and EMP proof...

The buzz is most likely a beacon used to home in ground based Satcom antennas. It would make sense to use short wave (HF) frequencies since they are pretty much immune to background radiation from a nuclear exchange.

I have Degrees in Electronics, and Communication Technology as well spending 10 years as an intelligence analyst.

LF and ULF is used in a post-nuclear environment (See more about SLFCS and the Green Pine systems) Also, use your search engine for more about the old GWEN networks.

The impact of scintillation effects on HF communications in a poststrike communications environment are complex, see Chapter 22.
